Holy shit.
You people make it seem like the guy wants to cut down after bulking up.
No.
He wants to lose weight because he's fat. He doesn't want to lose weight because he a) Wants to get into a weight qualification for a sport or b) To go to the next Mr. Olympian.
He simply wants to lose weight so he doesn't look like a landwhale.
The best way for that to happen is to get into a routine, both eating routine and a exercise routine. It's the same for all the hungry skellingtons who want to get gains, get into a routine of eating more, more frequently.
Like there's two very simple rule though; Don't eat junk food and stop drinking soda. Pretty self explanatory.
Oh and somehow people think that carbs are evil...?
They aren't. Starvation is a bad way to lose weight, don't do it. People who starve themselves basically just fuck up their metabolism, so yeah, you can lose all your weight, but as soon as you go back to a normal diet "oh shit where did all these kg's come from?". You'll also feel like utter shit so, yeah, don't do it.
